RUBBER HEEL.

Application filed March 14, 1923. Serial N'o. 625,008.

To (LZZ whom it may conccfm Be it known that I, ALBERT B. LYWITZKI, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Rubber Heels, of which the following is a specification.

This invention relates to improvements in cushioned heels and has forits prime object to provide a detachable heel that will reduce to aminimum the shocks received when Walking upon a hard footing Withleather heels or rubber heels of the usual construction.

A further object of the invention is to provide a cushioned heel whereina rubber heel is provided with a recess in which are provided a seriesof independent springs so that when the rubber portion of the heelbecomes useless, the springs can be inserted in a new heel and are readyto be fastened to the heel of a shoe.

A still further object of the invention is to provide means whereby theindependent springs and the rubber heel may be quickly attached andfastened to the heel o-f a shoe.

And a further object of my invention is to provide a cushioned heel ofthe above indicated character, which is simple in construction, durable,eicient for the purpose intended, and one that can be manufactured andplaced on the market for sale at a relatively low cost.

These and like objects of the invention will be better understood as thedescription follows and as is specifically pointed out in the appendedclaims.

Referring to the accompanying drawing which forms a part of thisspecification and which clearly illustrates the construction andOperation of my invention,

Figure 1 is an enlarged vertical sectional view of a shoe heelconstructed and attached to a portion of a shoe in accordance with myinvention.

Figure 2 is a section taken on line 2-2 of Figure 1, and

Figure 8 is a section taken on line 3-8 of Figure 1.

Referring to the accompanying drawing in detail, like characters will beused to designate like parts in the different views.

In the drawing, the numeral 1 indicates rubber heel of the usualconstruction, except that in carrying out my invention the upper face ofthe rubber heel or the part which engages the heel of a shoe is providedwith a recess 2, in which is positioned a plate 3 that conforms to theshape of the recess 2. A second plate et similar in construction toplate 3 is also positioned Within the recess 2, and a. series of coilsprings type of nails used for this purpose. The

nails 8 pass through the tread of the heel 1 and then through anaperture formed in the plate 3, upwardly through the coils of thesprings 5, through the aperture formed in the upper plate et and thenengage the heel and sole of the shoe 7, after which the point of thenails is bent downwardly so as not to annoy the wearer of same.

As soon as the rubber heel l becomes worn and is unfit for further use,the heel as a whole is removed from the shoe, at which time, the plates3 and 4 and springs 5 are removed from the old heel and inserted in anew heel, thus allowing same to be used many times.

In view of the foregoing description of my invention taken in connectionwith the accompanying drawing, it is thought that any furtherexplanation as to the construction, Operation, and objects of same, isunnecessary.

While I have shown and described the preferred form of my invention, 1realize that various minor changes may be resorted to without departingfrom the spirit and scope of the invention as claimed, and therefore, Ido not wish to limit myself to the exact details of construction shown,nor to the combination and arrangement of parts.

What I claim as new and desire to secure by Letters Patent is:

1. A cushioned heel comprising a body portion formed of rubber andhaving a recess formed in its upper face, a plate conformng to the shapeof the recess supported therein, a series of cushioning springssupported on said plate, a second late adapted to conform to the shapeof tie recess and similar in Structure to the first mentioned plateadapted to be supported by the cushioning springs, each of said platesbeing provided with an enlarged central Opening a plate having f anenlarged central Opening therein received in the recess forined in saidheel, said plate also having small openings for permitting said Vpins topass therethrough, and springs arranged about said pins and between saidplate and shoe.

In testiinony Whereof, I have afi'ixed my' Signature in the presence oftWo Witnesses.
